Crisis on Infinite Earths was the culmination of 8 years and almost 30 Seasons across all the series that make up the “Arrowverse”. Starting back in 2012, Arrow was The CW’s next move with a DC Comic property following the 10 year long run of Smallville coming to an end in 2011. Back then it was clear the creatives at both Warner Bros. and The CW were confident that Arrow would be a success.
